WIND OW SEAT.

Application led August 23, 1926.

My invention relates to improvements in window seats and has for itsobject the provision of an improved construction of this character whichmay be readily applied to any findow sill and securely locked thereto.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Fig. 1 is a sectional view through a window sill showing` a seatembodying the invention in position of use;

Fig.' 2 a top plan view of the seat removed and folded flat fortransportation;

Fig. 3 a top plan view of the seat member extended and attached to thewindow sill; and

Fig. l an inner face view of the seat detached.

The preferred form of construction as n, illustrated in the drawingscomprises a seat board 5 of convenient size and length provided withside rails 6 secured to the under side thereof flush with the ends andprojecting at one edge to form notches 7 as shown in Fig. 1. l The seatboard .5 is provided with two clamping bars 8 having hooks 9 at theirprojecting ends adapted and arranged to engage the inner ledge of awindow sill as shown in Fig. 1. At their other ends the clamping bars 8are pivotally and slidably secured to the seat board 5 by means ofhead,- ed studs or screws 10 engaging through elonlgated slots 11 andwhereby said clamping bars may have both sliding and pivotal movementrelatively to the seat board. Each clamping bar is provided at its inneredge with a plurality of lateral notches 12 adapted and arranged toengage headed studs 13 on the seat board to lock the clamping bars inadjusted positions. By this arrangement it will be noted that the seatboard may be rested on the outer portion of a window sill and theclamping hooks 9 engaged with the inner ledge of the window sill, saidclamping 4, bars being readily adjustable to lit different sizes orwidths of window sills.

A. back rest 14ris also provided for the seat, said back rest carryingside arms 15 normally resting when in use in the notches i' as shown.The lower ends of the side bars Serial No. 130,824.`

the corresponding side rails 6, and each link Y 16 is also'connccted bymeans of the slot 17 and screw 18 with the corresponding end of the seatmember. The upper portion of each side bar 15 is pivotally connectedwith a brace link 19 cooperating with a corresponding brace link 20,which in turn is given av slot and pin connection 21 with thecorresponding side rail 6, said links 19 and 20 beingY pivotallyconnected together at 22 to constitute a knee joint. The arrangement ofthe links is such that the back member may be readily extended into theposition shown in the full lines in Fig. 1, or folded flat forconvenience in transportation as shown by the dotted lines ink Fig. 1.Itwill also be observed that when the back member is in extendedposition the links Contact with the outer edges of the clamping bars 8and thus prevent disengagement of said clamping bars from the studs 13,so that when said window seat is occupied it is impossible for the sameto become detached from the window sill.. `When the back member 141-, ispartially folded, the clamping bars will be released, thus permittingfolding into the position illustrated in Fig. 2 Vfor convenience intransportation. In this way it will be noted that the window seat andclamping bars may be readily folded'when desired into compact form fortransportation. The specific form and arrangement of parts is a simpleand effective one for the purpose.

l/,Vhile I have illustrated and described the preferred formofconstru-ction for carrying my invention into effect, this is capableofy variation and modification without departing from the spirit of theinvention. I', therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scopeof the appendedclaims. p
